Dear all, I have been trying to compile some code (adcirc+swan) in mingw on windows, one win 10 and one win 7. I failed on both of them. For win 10, I even could not run the example case cpi by mpiexec -n 4 cpi. it says "error while connecting to host, no connection could be made because the target machine actively refused it. (10061)". I tried many solutions, including turning off the firewall, turning off the UAC, add a environment variable MPIR_CVAR_CH3_PORT_RANGE to specify the port to the same port that the mpi listening to... Non of them work. For win 8, don't know what reason I could successfully run the example case cpi by mpiexec -n 4 cpi. However, when I try to compile the code there's another error: launch failed: CreatProcess(work -I ../prep -O2 "-mcmodel=medium" -ffixed-line-length-none "-march+cori7-avx" -m64 -static -DREAL8 ............some flages here............ padcirc odir4/mkdir.o) on 'GodMapleTree' failed, error 5 - assess denied. I tried something, e.g., turn off the UAC, give the administrator assess, ... I just won't work. I know very little on the MPI. Could someone give me some tapes? -- Best regards, Yi Pan, PhD, Assistant Professor, College of Harbor, Coastal and Offshore Engineering, Hohai University, 1 Xikang Rd., Nanjing, Jiangsu 210098, China _______________________________________________ discuss mailing list [email protected] To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss
